This flaw, identified as CVE-2023-52945, allows a local attacker to execute arbitrary code on the system. The vulnerability exists in versions prior to 1.3.2-13814. An attacker can exploit this by placing a malicious OpenSSL DLL in a directory that BeeDrive searches before the legitimate system directory. Due to the BeeDrive application loading the DLL, the attacker’s code will be executed within the context of the BeeDrive process, potentially granting them elevated privileges or access to sensitive data. This vulnerability poses a significant risk to systems where BeeDrive is installed, as it can be exploited to compromise the system’s integrity and confidentiality.

Attack Chain

  1. The attacker identifies that Synology BeeDrive loads an OpenSSL DLL component.
  2. The attacker determines the DLL search order used by BeeDrive, likely by observing process monitor logs.
  3. The attacker creates a malicious OpenSSL DLL that contains arbitrary code to be executed.
  4. The attacker places the malicious DLL in a directory that BeeDrive searches before the legitimate OpenSSL DLL location (e.g., the application directory, a user-controlled directory in the system’s PATH).
  5. The attacker launches Synology BeeDrive.
  6. BeeDrive loads the malicious OpenSSL DLL from the attacker-controlled directory instead of the legitimate one.
  7. The attacker’s arbitrary code within the malicious DLL is executed within the context of the BeeDrive process.
  8. The attacker gains control of the BeeDrive process and can perform actions such as escalating privileges, stealing credentials, or installing malware.

Impact

Successful exploitation of CVE-2023-52945 allows a local user to execute arbitrary code with the privileges of the BeeDrive application. This could lead to complete system compromise, including data theft, installation of malware, or denial of service. Since the vulnerability can be exploited by any local user, it increases the attack surface for privilege escalation. The impact is high due to the potential for arbitrary code execution and the ease of exploitation.

Recommendation

  • Upgrade Synology BeeDrive for desktop to version 1.3.2-13814 or later to patch CVE-2023-52945.
  • Implement file integrity monitoring for BeeDrive’s installation directory to detect unauthorized DLL modifications.
  • Deploy the Sigma rule Detect BeeDrive Suspicious DLL Loading to identify potentially malicious DLLs loaded by BeeDrive.
  • Enforce strict access control policies to limit user access to sensitive directories and files, mitigating the impact of local privilege escalation.
